MOTOR-CYCLE STAND.

Specification of Letters Patent. Application filed July 1, 1911.

Serial No. 636,532.

To all whom it may concern:

Be it known that I, SAMUEL T. STEIN- nnnonn, a citizen of the UnitedStates, residing at Peoria, in the county of Peoria and State ofIllinois, have invented certain new and useful Improvements in Motor-Cycle Stands, of which the following is a specification.

My invention relates to motor cycle stands.

More particularly my invention relates to a telescoping section stand;means for controlling the telescoping relation, and a shoe at the baseof the stand.

The purpose of my invention is to provide a stand to normally supportthe weight of the wheel so that parts thereof will telescope relativelyunder the weight of the rider under a controlled tensionto permlt thewheel to engage a shoe at the base of the stand to cause a forwardimpetus to be given to the motor cycle and to cause the stand itself tobe thrown, by the momentum imparted thereto, by the movement of thewheel alone or by auxiliary appliances, to cause the stand to be lodgedin its support adjacent the mud guard.

My invention embraces a telescoping sectional stand made in any desiredform, a shoe at the base thereof, and means for controlling thetelescoping action of the parts of the stand.

In the drawingsFigure 1 is a side ele vation of a portion of a motorcycle frame and a wheel, showing my invention applied thereto; Fig. 2 isa rear view of a motor cycle showing my invention applied; Fig. 3 showsin elevation telescoping portions of the stand, the cylinder portionsthereof being shown in section on the line 3-3 of Fig. 2; Fig. 4 is asectional view on the line M of Fig. 1 and shows the relative positionof the wheel to the shoe when sup porting the motor cycle only and whenun- Fig. 5 shows parts of the stand, the tube portion thereof beingbro-ken away to show the relation of the parts. Fig. 6 is a detail viewshowing a portion of a spring cut off associated therewith.

To the extent of my knowledge and according to my information, standshave heretofore been employed to supportmotor cycles at starting thatwill permit the engine to be started while the machine is at rest. In sostarting, the rider mounts the the usual machine, starts the motor, thendismounts and disengages the stand or swings it to its supportedposition adjacent the mud guard, then, after a manually induced momentumis imparted to the wheel, the rider mounts and the clutch is thrown into propel the vehicle.

So far as I know, I am thefirst to provide means for controlling thestart from a stationary shoe, a controlled lowering of the motor cyclewheel to engage the shoe and by the action resulting from the engagementbetween the wheel and the shoe, the establishment of a temporaryinclined plane to impart the initial impetus to the wheel that isnecessary in starting.

Referring to the drawings, v2 indicates frame; 3 refers generally to themotor cycle wheel; 4 refers to the spindle or extension from the wheelaxle proper to which ordinarily stands are pivoted.

5 refers generally to the motor cycle stand.

6 is a frame part of the stand adapted to be pivoted to spindle at, saidframe part being provided, with an interior opening 7 (see Fig. 5).

8 is a frame rod having telescoping relation with the interior opening 7offrame part 6, said rod being connected with the base or crossconnecting portion 9 of the stand. r

10 isa frame part connected in the same manner withspindle 4 as framepiece 6, and providedwith a similarinte'rior' opening.

8 is an arm connected with frame 2 and adapted to bear against framepart 10 as a brace for the latter in supporting the rear portionof themotor cycle.

11 are rods or bars, the upper portion thereof having the same characterof telescoping relation with frame part 10 as rod 8 has with frame part6, the lower portion thereof being connected with the base 9.

12 isa shoe which may be in any desired form in cross section to bestengage the tire of wheel-3, and may be of any length desired, and ispreferably formed with a forward incline at its forward end to minimizeas much as ground.

For the purpose of providing for con trolled telescoping relationbetween the sections of the stand, I have provided cylinders PatentedOct. 1,1912.

possible the jar attending the passage of the wheel from the shoe to thein Fig. 1.

13 and 14, each connected with rods or bars 11 by means of brackets as15 and each provided with a piston opening as at 16, and cylindzer 1 1provided with air outlet opening 1 18 are piston rods having a fixedconnection with frame part 10.

19 and 20 are piston heads adapted to reciprocate respectively incylinders 13 and 1 1.

21 is a coil spring in cylinder 13 and 22 is a coil spring in cylinder14.

23 is a connecting duct or pipe from the opening into the lower part ofcylinder 13 into the upper part of cylinder 14. Normally enough liquid(preferably oil) is supplied to the controlled mechanism to fillcylinder 13, duct 23, and the small space above piston head 20 incylinder 1 1.

24" is a check valve designed to be operated by any suitable meanswithin convenient reach of the motor cycle rider, to cut off or permitthe flow of liquid from one cylinder to the other, and to control theflow therebetween.

25 is a graduated plate adapted as an indicator, for setting the valveto control the flow of liquid through duct 23 for the purpose ofequalizing the descent of the wheel under varying weights of riders. 26is also a control valve, the same being adapted to be connected to oneof the leaves of coil spring 21 and is formed V-shaped at its lower end,and adapted to bear over the inlet into duct 23. This valve is providedas a general control, independent of valve 24, which will prevent a tooviolent or quick descent of the motor cycle, as it will gradually reducethe size of the inlet opening into duct 23 as piston 19 descends.

In the operation of the device, the parts thereof are designed to beassembled relatively in substantially the positions shown in thedrawings, and in a position to support the motor cycle, substantially asshown The valve 2 1 having first been turned to cut off the flow betweencylinders 13 and 14., the rider may mount the motor cycle and start hisengine. Then, by turning valve 2 1- to permit a flow between cylinders13 and 1 1, the combined weight of the motor cycle and the rider willcause the piston heads 19 and 20 to descend from their normal positionshown in Fig. 3, respectively in cylinders 13 and 1 1, under the tensionof springs 21 and 22, and against the frictional resistance of liquid incylinder 13 passing through duct 23 into cylinder 14, and the resistanceof the gradual closing of the valve 26. The resistance of the graduallyclosing valve will, according to the setting of valve 24, be greater orless, according to the weight of the rider. The wheel will descend untilit strikes shoe 12 and the revolution of the former under the force ofthe motor will cause the wheel to be forwardly projected, passing fromthe shoe to the ground. As soon as the wheel releases the shoe, andstrikes the ground, the cycle stand frame will be free to move upon itspivot and the frictional engagement between the wheel and shoe willcontinue long enough under the frictional resistance of the liquidpassing from cylinder 14 through duct 23, to cause the stand to beturned with the wheel until it engages stand lock 27. hen the stand isrelieved from the weight of the machine and the rider, the springs 21and 22 will cause the lower portion of the frame and cylinders to bemoved until the piston heads are in the normal position shown in Fig. 3,at which time the parts of the device are in the proper relativeposition to allow the valve to be closed, with the stand elongated toits proper supporting form. The valve need not be closed until it isagain desired as a support for the motor cycle. In general and ordinaryuse, the valve 26 will control the fiow between the cylinders 13 and14:, therefore in such general usage, valve 2 1 need only be used as acomplete cut-01f or entire opening of communication between therespective cylinders.

I have described one form of embodiment of my invention but obviously itmay be differently formed and the arrangement of the parts modified, andthe same or sub stantially the same results attained. I therefore desireto claim all embodiments of my invention that legitimately fall withinthe scope of the same.
